5.1 TROUBLESHOOTING
Many technical issues can arise when converting a standard computer into a digital audio workstation (DAW).
PreSonus can only provide support for issues that directly relate to the FireStudio Tube interface and Studio
One Artist software. It may be necessary to contact the manufacturer of the computer, operating system, and
third-party DAW software to obtain additional technical support. PreSonus does not provide support for issues
regarding operating systems, additional hardware, or non-PreSonus software. Please check our Web site,
www.presonus.com , regularly for software information and updates, firmware updates, and technical support.
You also can get technical assistance by calling PreSonus at 225-216-7887 Monday through Friday between the
hours of 9 a.m. and 6 p.m. Central Time. PreSonus Technical Support can also be contacted during the same
hours via email at [email protected].
Pops and Clicks
Pops and clicks in either your input or playback audio are typically caused by momentary losses of
synchronization between the FireStudio Tube and its clock source. This can be due to a FireWire card that is not
suited for FireWire audio devices or to a lack of CPU power or available memory. Try closing all unnecessary
programs, increasing the buffer size in the Universal Control, and optimizing your operating system for audio.
Pops and clicks exclusive to the digital inputs or outputs are typically caused when the FireStudio Tube is not
digitally synced to the external digital device. If this is the case, ensure your FireStudio Tube and external
digital device are properly synced.
Please consult your external device’s user manual for details on syncing it to
your FireStudio Tube.
Flashing Sync Light
The FireStudio Tube’s Sync light flashes red and blue when it is not synced. Check the FireWire cable to ensure
that it hasn’t become disconnected.
Audio Dropouts
Audio dropouts can occur when the speed of your processor cannot buffer audio fast enough. Increase your
buffer size in the Universal Control and try the different Operation Modes.
No Input Signal on Channels 1-8 or 15 and 16
1) Check your mic cable. This should typically be an XLR connection.
2) Make sure the microphone does not require phantom power. If it does, press the 48V button.
